Do you very often organised the slide-show demos or presentation and sometime need to focus any particular area of the Screen to show cause the more attention of the viewers. This could be a problem for you as there was not any direct solution available but here I will introduce you with a new small tool which will solve your problem.
The tool is called MouseShade and is useful for all those who undergo lot of presentations or demos. If turned on, it dims the screen and puts a spotlight on the area around the mouse pointer, easily guiding the audience attention to an area of interest. The shade can be minimised, giving a clear view of the whole screen, and can then be reactivated when you need to highlight a specific part of the screen by clicking the Show option on the menu. This spotlight can also be very useful if you are creating any video presentation or any tutorial by shadowing unnecessary area.
This is also a very highly customizable that even the colour, size and opacity of the spotlight can be varied as per the needs keeping the light conditions in and around the area or as per the needs. The specified settings will be automatically saved the next time even if the application is closed.
